Hackers Help: Hiding stackable top-load washer/dryer in AKURUM high cabinet


I have long admired the ikeahacking work here — and now I need help! I want to hide my stackable washer/dryer inside an AKURUM cabinet. They are too deep of course, and I need to be able to roll out the washer.

Can I just leave the back ‘undone’ — and not put in a toe-kick?

Here are the dimensions of the washer dryer and I’ve included a picture.
24″ W x 78″ H x 31″ D


Any help would be appreciated… especially since I’ve already bought the cabinet!
